TENSION nnvron.

Application filed January 4, 1918. Serial No. 210,331.

To all whom it may concern I Be it known that we, JOHN F. Rnannon, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, and EMMnRIon H. Knrsrnk, a citizen of the United States, residing at Thompson, in the county of Vindham and tate of Connecticut, have invented certain new and useful Improvementsin Tension Devices, of which the following is aspecification.

This invention relates to improvements in tension devices for use in connection with bobbins, cops, roquets and the like and it is the principal object of the invention to provide a device whereby the thread or other strands of material will be placed under sufficient tension during the loading or doifing of the bobbin, etc., to prevent tangling and the resultant rupturing of the thread.

It is a more specific object of the invention to provide a tension device of the character mentioned formed of low frictional material and having an even bearing surface whereby the thread, yarn or the like will be allowed to move freely thereover without liability of rupture.

Among other aims and objects of the invention may be recited, the provision of a device of the character mentioned with a view to compactness, and in which the number of parts are few, the construction simple, the cost of production small, and efficiency and operation high.

The improvements in the details and ar rangement of parts will be apparent rom an inspection of the accompanying drawings, in connection with the specific description hereinafter contained, and wherein the preferred embodiment of the invention is disclosed for the purpose of imparting a full understanding of the same.

In the drawings Figure 1 is an elevation of the improved holder,

Fig. 2 is a similar view of the same taken at right angles to the Fig. 1, and

Fig. 3 is a vertical section through the tension means and a portion of the bracket.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Having more particular reference to the drawings, 1 represents the supporting bracket in 1ts entirety, the lower portion of Specification of Letters Patent.

. mediate portion of the same,

' is passed upwardly from the bobbin or on the bearing pintle Patented Feb. 3, 1920.

which is off-set to provide base portion 2, while the upper end of the same is off-set as at 3 to provide a supporting arm, the free end of which is apertured and receives therethroughone end of a bolt at the purpose of which will be subsequently described; it be ing noted in this connection, that the said bolt is secured rigidly to the arm 3 by means of locking nuts 5. i

An upright bearing pintle 6 is arranged upon the ofl-set base partion 2 and rotatably supports a bobbin-7, or a spool or other suitable device. To permit the bracket 1 to be secured to a suitable support, laterally eX- tending arms 8 are formed upon the interone of the said arms being apertured and receiving a locking or clamping set-screw 9 therethrough; the said screw obviously, being turned into engagement with the device to which the bracket is attached.

Disk like members 10 and 11 having conon the bolt 4 and receive therebetween a ton sion device 12 formed of glass or'other suitable low frictional material and having a concaved peripheral surface free of scams or the like. To insure proper engagement of the disk like members 10 and 11 with the tension device 12, the adjacent portions of the same are provided with annular flanges and receive therein gaskets 13 formed of felt or other similar material, which gaskets, as will be noted, receive the adjacent marginal portions of the said tension device thereon, thereby preventing rattling or other undue movement of the same. Further, a spring thrust member let is arranged upon the outer end of the bolt 1- andis engaged with the adjacent side of the disk like member 10 through the medium of a locking nut 15.

Guide hooks 16 and 17 areformed integral with the peripheral portions of the disk like bodies 10 and 11; the element 16 being of a length slightly greater than the element 17; The thread, yarn or other strand of material like device supported through the guide element 16 then about the tension device and thence through the hook or guide elements 17 to the device feeding or receiving the same. Obviously, in this way, proper movement of the thread with relation to the bobbin is caused.

From the foregoing, it will be readily un derstood by Workers skilled in the art that we have provided an exceedingly simple and efficient tension device which may be adapt- L ed for use in connection with practically any Furthermore, by forming the tension device of low frictional material, the splitting or tearing of the thread, yarn or other material engaged therewith is positively prevented.

Manifestly, the construction shown is capable of considerablemodification and such modification as is'within the scope'of our claim we consider within the spirit of our invention.

We claim A holder of thecharacter described including a standard, afrangible cylindrical tensioning device provided with a concave peripheral surface, clamping members arranged at the opposite ends of the tension device, circular inwardly directed flanges receiving the terminal portions of the tension device, a bolt passing axially through the clamping members, means rigidly connectin one of the clamping members with the stan ard, the other clamping member being movably mounted upon the bolt, cushioning elements confined Within the flanges of the clamping members and interposed between )JOHN F. REARDON.
